D4: Frequency Reference Hold And Up/Down 2 Function - YASKAWA A1000 Technical Manual

<1> In AOLV/PM and CLV/PM control modes, the setting units and range are expressed as a percent (0.0 to 100.0%) instead of in Hz.
<2> In AOLV/PM and CLV/PM control modes, the setting units and range are expressed as a percent instead of in Hz. The Setting range is 0.0 to
40.0% and the default is 1.0%.
Figure 5.47 shows the relationship between the Jump frequency and the frequency reference.
Figure 5.47
Note: 1. The drive will use the active accel/decel time to pass through the specified dead band range, but will not allow continuous operation
in that range.
2. When setting more than one Jump frequency, make sure that the parameters do not overlap.
 d4: Frequency Reference Hold and Up/Down 2 Function

d4-01: Frequency Reference Hold Function Selection
This parameter is effective when either of the digital input functions listed below is used.
• Accel/decel ramp hold function (H1-= A)
• Up/Down function (H1- = 10 and 11)
• Up/Down 2 function (H1- = 75 and 76)
Parameter d4-01 determines whether the frequency reference or the frequency bias (Up/Down 2) value is saved when the
Stop command is entered or the power supply is shut down.
No.
d4-01
The operation depends on the function used with parameter d4-01.
Setting 0: Disabled
• Acceleration hold
The hold value will be reset to 0 Hz when the Stop command is entered or the drive power is switched off. The active
frequency reference will be the value the drive uses when it restarts.
• Up/Down
The frequency reference value will be reset to 0 Hz when the Stop command is entered or the drive power is switched
off. The drive will start from 0 Hz when it is turned back on again.
• Up/Down 2
The frequency bias is not saved when the Stop command is entered, or 5 s after the Up/Down 2 command has been
released. The Up/Down 2 function will start with a bias of 0% when the drive is restarted.
